Avoiding Obstacle Based On Active Secuirty

With the hign development of the vehicle industry, it will be very convinence forthe hunman’s living. But at same time it also takes some traffic problems. The trafficproblem maybe is the most important problem. So the reasearch of the active safetybecome the hospot and avoiding obstacle aiming for safety also become one of thehospots. This paple discusses something about avoiding obstacle and the mainly contentas follows:Reading large range of information not only inland and oversees and have moreacquaintance about the safety tecnology then reading back knowledge about the activesafety. Building the vehicl power model movement model and oppsite power model(opposite engine model and braking model) and connect the knowledge planing all theproject of avoiding obstacle. Choosing the Fuzzy PID methods to control avoidingobstacle because of the long delay and unlinear.The power model movement model and oppsite power model (opposite enginemodel and braking model) under the condition of Matlab/Simulink are builded.Different position chooses different methods. Design proportion control fuzzy PID andfuzzy methods control the braking and oiling. And the result will be up to grade.
